ET's Thea Andrews talks to Denzel Washington at Comic-Con 2009 -- and he reveals some set secrets, including what it took to engage in the action-packed, post-apocalyptic beatdown on hoards of feral bad guys in his upcoming film 'The Book of Eli.'

Denzel also tells Thea why appearing at Comic-Con is so rewarding for him, pointing out the enthusiasm and dedication of fans who came out in support of his new film.

In the 'The Book of Eli,' which explodes into theaters next January, Denzel plays a lone warrior named Eli, who determines that it's his destiny to bring civilization back from the brink of destruction -- and save the future of humanity. The movie also stars Gary Oldman, Jennifer Beals and Mila Kunis and is directed by Albert and Allen Hughes ('From Hell,' 'Dead Presidents').
